Description
Bently Nevada 330190‑040‑00‑RU — 3300‑XL ETR Extension Cable (Russian EAC Variant)
Product Overview
The 330190‑040‑00‑RU is an Extended‑Temperature‑Range (ETR) coaxial extension cable for Bently Nevada 3300‑XL 8 mm proximity transducer systems. The suffix ‑RU represents regional variant with EAC conformity documentation for Russian‑Federation import and site acceptance; the electrical and mechanical hardware remains identical to standard 330190‑040‑00‑00. This cable connects proximity probe pigtail to proximitor / 990‑series transmitter, transmitting high‑frequency eddy‑current sensor signals for shaft‑relative vibration, thrust‑position and Keyphasor measurements. ETR insulation allows stable operation in high‑temperature casing‑adjacent environments where standard‑grade cables would degrade prematurely. Compliant with API‑670 turbomachinery protection requirements.
Critical Compatibility Warning
- Exclusively for 3300‑XL 8 mm Microdot‑interface proximity probes and proximitors. Not compatible with NSv / ClickLoc transducer hardware.
- Total transducer system length = probe integral pigtail length + this extension cable length, must strictly match the calibrated length requirement of proximitor / transmitter. Mismatched total length causes scale‑factor drift and measurement inaccuracy.
- Both cable ends are Microdot coaxial connectors. Do not splice, cut or modify factory molded cable assembly.
- The‑RU suffix only provides EAC import documentation; hardware intrinsic‑safety rating follows base‑model specification, verify label before hazardous‑zone installation.

Installation and Configuration Guide
Warning: Installation must be completed by qualified instrument technicians. Always refer to original Bently Nevada 3300‑XL transducer‑system manual as primary reference. Verify intrinsic‑safety marking before deployment in explosive classified hazardous zones.
- System Length Calculation Pre‑Check
- Calculate total transducer length = probe integral pigtail length + 4.0 m of this extension cable.
- Confirm total length exactly matches the calibrated‑length requirement of the installed proximitor or transmitter. Length mismatch creates scale‑factor error.
- Cable Routing Requirements
- Route ETR coaxial cable separately from high‑power AC, VFD and contactor cables to minimize EMI interference.
- Maintain minimum static bending radius ≥50 mm; avoid sharp kinks. Do not pull cable by connectors.
- Where cable passes through machine‑case wall, use approved cable‑seal assembly (43501‑02‑04‑02). Prevent mechanical crush and abrasion damage to outer insulation.
- Connector Mating Procedure
- Clean Microdot connector contact surfaces before connection. Align pin‑keyway correctly, tighten to manufacturer‑specified torque value. Never force connector engagement.
- Provide cable strain‑relief via clamps; avoid mechanical tension transferred directly to Microdot connectors.
- System Commissioning
- Complete full transducer loop assembly, power‑up proximitor / monitor hardware.
- Read static gap voltage to confirm probe gap setting. Perform static‑gap calibration test with 8 mm calibration fixture to validate system scale‑factor.
- Confirm Not‑OK fault status clears after proper wiring and gap adjustment.
- Maintenance & Troubleshooting
- During machinery turnaround, inspect Microdot connectors for oil contamination, dirt and corrosion. Check ETR insulation for heat‑caused hardening or cracking.
- Unstable gap‑voltage readings, high noise level or persistent Not‑OK faults may indicate damaged cable, bad connector contact or incorrect total‑system cable length.
- If cable is damaged, replace the complete factory cable assembly; field splicing or repairing coaxial cable is prohibited.
- Regional Documentation Note
- Model 330190‑040‑00‑RU is supplied with EAC conformity documentation for Russian‑Federation import and site acceptance. Electrical‑mechanical specifications are identical to base‑model 330190‑040‑00‑00.
Supplementary Remark
330190‑040‑00‑RU is a 4‑meter non‑armored ETR high‑temperature Microdot‑to‑Microdot extension cable for 3300‑XL 8 mm proximity‑transducer systems,‑RU suffix delivers EAC conformity documents for Russian‑market projects. It is incompatible with NSv / ClickLoc transducer hardware. Before commissioning, cross‑check total transducer‑system length, connector type, temperature rating and EAC‑RU documentation requirement against project BOM and mechanical drawings.
